ESTABLISHMENT OF STANDARDS FOR HIGHWAY NOISE

PURSUANT TO NOISE-RELATED RECOMMENDATIONS OF THE COUNCIL ON ENVIRONMENTAL QUALITY, RESEARCH WAS UNDERTAKEN WHOSE PRODUCT IS INFORMATION THAT WILL ALLOW HIGHWAY DESIGNERS TO PREDICT NOISE LEVELS EXPECTED FROM A NEW HIGHWAY FACILITY. THE RESULTS ARE CONSIDERED AN INTERIM SOLUTION TO THE RECOMMENDATIONS WITH RESPECT TO HIGHWAY TRANSPORTATION NOISE. TWO EQUATIONS WERE DEVELOPED TO EXPRESS THE NOISE PRODUCED BY A STREAM OF AUTOMOBILES AND TRUCKS, RESPECTIVELY. THE EQUATIONS ARE USED TO DEVELOP A DESIGN GUIDE THAT REQUIRES OF THE HIGHWAY DESIGN ENGINEER NO EXPERIENCE IN ACOUSTICS. TWO GRAPHS ARE PRESENTED PLOTTING AUTOMOBILE AND TRUCK VOLUME AND SPEED AGAINST AMBIENT NOISE LEVELS EXPRESSED IN DECIBELS. ANOTHER PRODUCT OF THE RESEARCH IS A TAPE RECORDING OF NOISE PRODUCED BY MOTOR VEHICLES. THE RECORDING WAS MADE TO ASSIST ENGINEERS TO UNDERSTAND HOW DIFFERENT NOISE LEVELS ARE HEARD, WHAT THE SIGNIFICANCE IS OF CHANGING NOISE LEVELS BY VARIOUS AMOUNTS, AND HOW MOTOR VEHICLE NOISE VARIES WITH TRAFFIC FLOW CONDITIONS.
